IMPROVEMENT IN SPIKE-MACHINES.

Specification forming part of Letters Patent No. 170,255, datedNovember-23, 1875; application filed April 5, 1875.

To all whom it may concern:

Be it known that I, WORCESTER HADDOOK, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Spike-Machines; and I do hereby declare that thefollowingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings and to the letters of reference markedthereon.

The nature of my invention consists in the combination of a heading-die,stationary die,

pointing and severing rolls, gripers, adjustable guide and stripper, anda conductor, all arranged and operating with relation to each other, sothat while the rolls have a continuous motion the spike-blank and thebar from which it is formed are held in a fixed position during theoperation of forming the head upon the spike, which is subsequentlyforced from the machine by the iron entering it for the formation ofanother blank and headed spike.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification,Figure 1 is a front end elevation of my improvement inspikemachines.Fig. 2 is a top view or plan of the same. Figs. 3 and 4. are side viewsof the same. Fig. 5 is a vertical and longitudinal section of the same.Fig. 6 is a detailed section.

In the accompanying drawings, A represents the frame of the machine. Band 0 represent the pointing and severing rolls. The roll B is furnishedwith a groove, 23, and de tachable dies y, and roll 0 is provided Withrecesses w and detachable dies :20. On the axis of the roll B is awheel, 8, which gears into a wheel, 7, on the axis of the roll 0. Thedies y and 00 of the rolls B and O are of such form, and so arranged inthe periphery of the rolls, that they will come together, as indicatedin Fig. 5, and thereby form the point on the spike-blank, and sever itfrom the bar indicated by dotted lines and marked 5. D represents theheader, which moves in slides l, and is moved up to its work by cams m,acting on the friction-roller f pivoted in the end of it, and is drawnback by means of a spring,

a. to which is attached a rod, 9, one end of which is connected at h tothe header. On the axis of the cams m is a wheel, 10, which gears into awheel, 9, which meshes into the wheel 6 on the axis of the cams s, whichoperates the griper F whlch holds the spikeblank up against. thestationary die g during the operation of forming the head upon it. Thestationary die has a recess in its face fronting the heading-die k,which recess corresponds to the desired form of the underside of thehead of the spike. The griper F, after it has performed its office ofholdin g the spikeblank in the stationary die g, is drawn down from theformed spike through medium of the spring t, rod u, and lever c, thelatter being attached to the axis of the griper. The header D isprovided with a detachable heading-die, k, which is held in it by aset-screw, Z, and is adjusted with relation to the stationary die 9 bymeans of the wedge i, which is held in a fixed position by the set-screwj. To the pivoted cross-bar n is secured an adjustable stripper andguide, h,which is adjusted and held in position by means of the bolt 3and screw-nut 4. The lower end of the stripper and guide enters thegroove t in the roll B, and presses against the bottom of groove,serving the purpose of the ordinary fixed stripper, and also acts as aguide for directing the iron into the stationary die 9. The stripper andguide it isheld to its work' by means of the spring 6, rod f, and levere, the

latter being attached to the axis of the cross-.

bar n. By this arrangement of the cross-bar, lever, rod, and spring, thestripper and guide It will yield to the contour of the bottom of thegroove t. The front end of the machine is furnished with a guide, m, andalso with a griper, E, which is held to its work by means of theprojections 19 on the periphery of the wheel 0 acting on the projection1 on the inner face of the arm 2 ot' the griper. The spring 7', actingagainst the lower end of the arm 2, will hold the griping-edge s of thegriper E up off the bar while being fed into the machine.

The wheel 0, represented in Fig. 6, is secured on the axis of the roll0, as indicated by the dotted lines in Fig. 5. The power for operat.

' the machine.

,ji'ng the machine is applied to the shaft 0" of thewheel 6, whichrevolves the wheels 7 and 9,

ber of teeth of each wheel must harmonize,-

so that all the wh eelscombined will give to the several parts of themachine the desired movement.

From the foregoing description, and by reference to the accompanyingdrawings of my improved spike-machine, the skillful mechanic willreadily understand the construction and arrangement of the severalparts, and the relation they bear to each other. I will, therefore,proceed to describe the operation, which is as follows: The bar 5, fromwhich the spikes are made, as it comes from the rolls in its last passthrough them,the endof the baris placed through the opening 0 of thegriper E, and

- enters the guide m and groove w of the roll B, and the surfaces t ofthe rolls B and G, impinging on the bar, draw and force it forward intothe stationary die g. The points of the dies y and as, coming directlyopposite to each other, (as shown in Fig. 5,) will nearly cut 011' theblank for the spike. At this point griper E impinges on the bar 5, andholds it firmly in the guide m. At the same time. rolls B and 0 continuetheir motion, causing dies 3 and w to sever the blank from the bar, andcarry it forward into the stationary die g, so that sufficient iron willproject beyond the vertical face of the die to form the head of thespike. At this point the griper F forces the blank up firmly against thestationary die g, holding the blank in a fixed position until the headerD moves up andforms the head upon the blank. The header then moves back,and simultaneous therewith the gripers E and F release their a hold onthe bar and formed spike, and the surfaces t again impinge on the bar 5,and draw it in for the formation of another blank and spike. The ironentering the stationary die 9 forces out the finished spike, which dropsfrom The recesses w, in the roll 0,

prevent the rolls B and C from impinging upon the bar, and allow therolls to have a continuous motion, while the blank and bar are held in afixed position during the operation of forming the head upon the spike.

Having thus described the nature, construction, and operation of myimprovement, What I claim as of my invention is 1. In a spike-machine,the combination of the pointing and severing rolls B and G, having acontinuous motion, the stationary die 9, gripers E and F, and the headerD, arranged and operating with relation to each other, so that the ironis fed into the machine, the blank for the spike pointed and severedfrom the bar,

and bar and blank held in a fixed position during the operation offorming the head upon the spike, substantially as herein described.

2. The yielding and adjustable stripper and guide h, in combination withthe roll B and stationary die g, substantially as herein described, andfor the purpose set forth.

3. In a spike-machine, the cams m, springrod 9, and header D, incombination with the rolls B G, stationary die g, and gripers E F,substantially as hereinbefore described and set forth. p

4. In a spike-machine, the wheel 0. spring 'r, and griper E, incombination with the rolls B G and header D, substantially as and forthe purpose hereinbefore described and i set forth.

5. In a spikemachine, the griper F, operated through the medium of thecams s, lever '0, rod u, and spring t, in combination with thestationary die 9, header D, and rollsB G, substantially as and for thepurpose hereinbefore described and set forth.
